This page shows what was measured, who it was measured in, and what that does not settle.

What Rituximab does in the body

Used for lymphomas and immune diseases involving a type of white blood cell.

B cells wear a badge called CD20. Rituximab is an antibody that grabs the badge and marks that cell for destruction by three different mechanisms at once. Blood stem cells do not wear the badge, so the B cell population is wiped out and then rebuilt from scratch over the following six to twelve months, often without the disease coming back with it.

What happened in people

Just under half of 166 people with returning low-grade lymphoma responded to four weekly infusions.

Words this page uses

Four words worth knowing first

Chosen from what this page shows, with each one explained before the word it depends on.

Protein

A protein is a folded chain your body builds to do a specific job.

A picture of it, and where the picture fails

A protein is like a tool bent into one shape for one task.

Where that stops being true. A tool keeps its shape. A protein can change shape and stop working.

What people get wrong. Protein in food and a protein in the body are related but not the same thing.

A polymer of amino acids folded into a defined structure that determines its function.

Enzyme

An enzyme is a protein that speeds up one chemical change.

A picture of it, and where the picture fails

An enzyme is like a machine on a production line doing one cut.

Where that stops being true. A machine is switched on and off by a person. Enzymes are controlled by the cell.

What people get wrong. Enzymes are thought to be used up. They are not; they work again and again.

A catalytic protein that lowers the activation energy of a specific reaction.

Receptor

A receptor is a part of a cell that a signal fits into.

A picture of it, and where the picture fails

A receptor is like a lock waiting for one key.

Where that stops being true. A lock either opens or does not. A receptor can be half-triggered, or worn out.

What people get wrong. Fitting a receptor is read as causing a benefit. It causes a step, and nothing more.

A protein that binds a specific ligand and converts that binding into a cellular response.

Pathway

A pathway is a chain of steps inside a cell, each one setting off the next.

A picture of it, and where the picture fails

A pathway is like a row of dominoes.

Where that stops being true. Dominoes fall one way. Pathways loop back and can switch themselves off.

What people get wrong. Changing one step is read as changing the outcome. Other steps often absorb it.

An ordered series of molecular interactions producing a defined cellular change.

What happened in peopleRead from sources, not yet reviewed

How close this is to real life

The top step is something a person would feel or care about. The bottom is a guess from software. Filled steps are where evidence exists for this substance.

  1. Living longer, or avoiding a major event Evidence recorded. Death, a heart attack, a stroke, a hospital stay.16 registered measures of this kind. No reviewed result.
  2. What a body can do day to day No evidence recorded. Walking, dressing, breathing, recovering.No registered study measures this.
  3. Measured performance No evidence recorded. How much was lifted, how far was run, how fast.No registered study measures this.
  4. Symptoms and quality of life No evidence recorded. Pain, tiredness, mood, sleep, as the person rated it.No registered study measures this.
  5. A number that stands in for health No evidence recorded. Cholesterol, blood sugar, bone density. A stand-in, not the thing itself.No registered study measures this.
  6. A step measured inside a person Evidence recorded. Something measured in human tissue or human cells.A human record sits on the stored organism ladder.
  7. Animals Evidence recorded. Mice, rats, dogs. Useful for ideas, not proof about people.Stored records in Mouse, Rat. A result in animals says what to test next. It does not say what happens in people.
  8. Cells in a dish Evidence recorded. Cells or chemistry on a bench, far from a whole body.Stored mechanism abstracts describe steps measured in cells or tissue.
  9. A guess from software No evidence recorded. Nobody measured it. RNAWiki never publishes one as a finding.RNAWiki stores no prediction for this record. Software can suggest a link. RNAWiki does not publish one as a finding.

Higher on these steps means closer to something a person would feel. It does not mean better done.

What it changes in the bodyRead from sources, not yet reviewed

The path through the body

From what a person takes to what changes. A solid line is a step measured in people. A dashed line is a step nobody has measured that way.

Where a source records it acting

  • Immune and lymphatic system: Targets the CD20 antigen expressed on the surface of pre-B and mature B-lymphocytes; upon binding to CD20 it mediates B-cell lysis

    US prescribing information · b172773b-3905-4a1c-ad95-bab4b6126563 · read 2026-08-28

  1. Start

    Rituximab

    What a person takes: Intravenous infusion, or subcutaneous injection co-formulated with recombinant hyaluronidase.

    The measurement behind this step

    Given as 375 mg/m2 weekly in lymphoma, 1,000 mg twice two weeks apart in rheumatoid arthritis, with a stepped infusion rate and mandatory premedication.

  2. Getting in

    Slow first infusion to manage cytokine release

    The first dose is given very slowly, because destroying a large number of B cells at once releases a wave of inflammatory signals that causes fever, chills and low blood pressure.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Standard dosing is 375 mg/m2 weekly in lymphoma or two 1,000 mg doses two weeks apart in autoimmune disease, with a stepped infusion rate and premedication with paracetamol, antihistamine and often a corticosteroid.

  3. Reaching the cell

    Reaching CD20 on B cells everywhere except the ends of the lineage

    It finds B cells in blood, lymph nodes, spleen and bone marrow. Stem cells and fully mature antibody-producing plasma cells do not carry the badge, so they survive.

    Measured in people. Written by a person from the study named beside the step. Not signed off as a reviewed claim.

    The measurement behind this step

    CD20 is expressed from the late pre-B stage through the memory B cell, but not on haematopoietic stem cells, pro-B cells or terminally differentiated plasma cells. That expression window is what makes depletion recoverable and why long-lived humoral immunity is partly preserved.

  4. What it acts on

    Binding the large extracellular loop of CD20

    The antibody grips a small exposed loop of the CD20 protein. CD20 is not shed and does not get internalised much, so the mark stays where it was placed.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Binds a discontinuous epitope on the large extracellular loop of the tetraspanning MS4A1 protein, driving CD20 into lipid rafts. Rituximab is a type I anti-CD20 antibody, which favours complement recruitment over the direct cell death that type II antibodies such as obinutuzumab preferentially cause.

  5. The change it makes

    Three separate killing mechanisms fire together

    Complement proteins punch holes in the coated cell, natural killer cells latch onto the antibody tail and destroy it, and macrophages swallow it whole.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    C1q binding to clustered Fc initiates the classical complement cascade and membrane attack complex formation; FcgammaRIIIa on natural killer cells drives antibody-dependent cellular cytotoxicity; FcgammaR-bearing macrophages in liver and spleen perform antibody-dependent cellular phagocytosis. Direct apoptotic signalling contributes less for a type I antibody.

  6. What that does for a person

    The B cell compartment empties, then slowly rebuilds

    Circulating B cells disappear within days and stay away for six to twelve months. When they return they are often naive cells that do not carry the disease with them.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Peripheral B-cell depletion is typically complete within three days and recovery begins at six to nine months, with repopulation dominated by transitional and naive subsets. In autoimmune disease the reconstituted repertoire is frequently less autoreactive, which is the leading explanation for durable remission after a finite course.

No suggested links are held for this record, so nothing is hidden from this path.

What we know
The record describes 5 steps from taking it to an effect in a person.
How we know it
Each step names the study behind it in the technical detail beside it.
What this does not prove
A change inside the body is a reason to look. It is not a result in a person.
Why it matters
A reader can see exactly where the chain stops being measured in people.
What we still do not know
No reviewed claim binds any of these steps to a named population.

What it would be like to takeRead from sources, not yet reviewed

Felt, measured, or meaningful

Three different things that get called the same word. Registered studies measured all three, and mixing them is how a blood test becomes a health claim.

Felt

Things a person could notice without a test.

No registered study measured anything of this kind.

Measured

Things only a test, a scale or a device shows.

No registered study measured anything of this kind.

Meaningful

Things that change how a life goes, not only a number.

  • progression free survival
  • overall survival
  • 2 year overall survival rates
  • 2 year progression free survival
  • time to disease progression
  • progression free survival at 1 year
  • progression free survival at 2 years
  • progression free survival at 5 years
  • overall survival at 2 years
  • overall survival at 5 years

and 6 more.

A registered study says what someone planned to measure. It does not say what they found. A number moving is not the same as a life going better. The two are shown apart here.

Felt, but not shown to help. A person notices a change. No study showed it leads anywhere good.

Measured, but not felt. A number moves. The person notices nothing. Both can be true.

Measured, but not shown to matter. A number moves in the good direction. Nobody showed that lives went better.

Matters, but takes years. The result that counts may take longer than anyone would keep watching.

Names that fit none of the three (24)
  • overall response
  • overall response rate
  • determination of safety profile and response rates
  • time to treatment failure
  • response rate
  • response to treatment
  • response

  • disease response
  • engraftment

  • systemic lupus erythematosus disease activity index
  • objective tumor response
  • complete response rate
  • graft failure
  • toxicity
  • grade 3 stomatitis
  • minimal residual disease
  • incidence of adverse experiences

These are harms, study-process measures, or names the rules did not recognise. They are shown rather than dropped.

How long anything takes

Nine different lengths of time that get confused with each other. None of them is worked out from another.

  1. Before anything is noticed. RNAWiki does not store this separately, and never works it out from another figure on this page.

  2. Before a test result moves. RNAWiki does not store this separately, and never works it out from another figure on this page.

  3. Before performance moves. RNAWiki does not store this separately, and never works it out from another figure on this page.

  4. How long the result was watched. No finished study window is recorded for a study that tested this substance.

  5. How long people took it. How long people actually took it is not stored. The study window is not the same thing.

  6. How long people were followed. Follow-up length is not stored separately. It is never read off the study window, which would be a different thing.

  7. How fast the body clears it. 22 days (range, 6.1 to 52 days)

    Read from the label, which states: “Based on a population pharmacokinetic analysis of data from 298 NHL patients who received rituximab once weekly or once every three weeks, the estimated median terminal elimination half-life was 22 days (range, 6.1 to 52 days).”

  8. How long effects linger. RNAWiki does not store this separately, and never works it out from another figure on this page.

  9. Beyond the studies. Nothing is recorded about the long term.

    The longest finished study sets the edge of what anyone measured.

A study window is not how long people took it, and neither is how long they were followed. Where RNAWiki holds only one of the three, it shows one.

What is missing or unclearRead from sources, not yet reviewed

Were people like you studied?

RNAWiki cannot tell whether a study fits you. It can show who was in it, and where the result stops carrying.

Who was studied

People similar to this profile were included.

  • People with CD20-positive B-cell lymphoma or leukaemia, and people with rheumatoid arthritis, ANCA-associated vasculitis or pemphigus not controlled by first-line therapy. It is also used off-label in multiple sclerosis, membranous nephropathy and other antibody-driven disease.

Who is missing from the studies

  • Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

What the label states about particular groups

  • On pediatric, the label states: “The safety and effectiveness of RITUXAN have not been established in pediatric patients with CLL.”

Where the result stopped carrying

  • EXPLORER and LUNAR both missed their primary endpoints in systemic lupus erythematosus and lupus nephritis
  • The chimeric construct retains murine variable domains, and human anti-chimeric antibodies remain a cause of infusion reactions and loss of response that fully humanised successors were built to avoid
  • This is a scope explorer, not a diagnosis engine.
  • It shows who was studied so you can see whether people similar to you were included.

RNAWiki cannot tell whether a study fits you. It can show who was in it.

What it would be like to takeRead from sources, not yet reviewed

Why it might seem to do nothing

A real effect and a noticed effect are different things. These are the recorded reasons the two come apart.

It was studied for a different goal

The studies measured something else entirely.

On this record: Some registered studies measured things that match no goal on this page.

It was studied in different people

The people in the studies were not much like the reader.

On this record: Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

The evidence may simply be wrong

Small early studies often do not hold up.

On this record: RNAWiki has not yet published a reviewed conclusion for this use.

Other reasons RNAWiki checked and found nothing for (10)
A different form was studied
The studied form is not the form on the shelf. Nothing in this record points to this reason.
There was nothing to correct
Where a level is already normal, topping it up may change nothing. Nothing in this record points to this reason.
Something else had to happen too
In the studies it was paired with training, a diet or another treatment. Nothing in this record points to this reason.
The change is too small to feel
A real change can still sit below what a person notices. Nothing in this record points to this reason.
Day-to-day swing hides it
Sleep, food, stress and time of day move most numbers more than this would. Nothing in this record points to this reason.
Not enough time yet
The studies ran longer than the person has waited. Nothing in this record points to this reason.
It was not taken as studied
Missed days change the result, and studies count them. Nothing in this record points to this reason.
Something else changed at the same time
Two changes at once cannot be told apart afterwards. Nothing in this record points to this reason.
The product may not be what it says
Contents of a sold product are not always what the label states. Nothing in this record points to this reason.
No recorded reason
RNAWiki has nothing stored that would explain it. Nothing in this record points to this reason.

None of these is a reason to take more. Taking more is not a step this page ever suggests.

What you could measure

This one is decided with a clinician, so this section holds questions to ask rather than a plan to run.

Self-experiment planning is not offered for a prescription or clinician-supervised medicine. The questions below are for a clinician or pharmacist.

Questions worth asking

  • Which of the trials of Rituximab studied people like me?
  • What was measured, and for how long?
  • Was the result a laboratory value or a health outcome?
  • What would we watch for, and when would we stop?

Tracking can show whether something changed for you. It cannot show what caused it.

RNAWiki records evidence. It does not say whether this substance is right for you.

What is missing or unclearRead from sources, not yet reviewed

Claims that go past the evidence

Things said about this substance that sound reasonable, and the exact step that is missing between the evidence and the claim.

Goes past the evidence

That B-cell depletion helps in any B-cell-mediated disease; lupus is the counterexample where two randomised trials failed

Why it sounds right. It follows from something real on this page: a body step, an animal result or a related finding.

McLaughlin 1998: a 48% response rate as a single agent in relapsed indolent lymphoma
In plain words
The trial that made rituximab the first antibody approved for cancer. Just under half of 166 patients with relapsed low-grade lymphoma responded to four weekly infusions, with mostly mild toxicity.
What was measured
Objective response rate 48% on intent-to-treat
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
Multi-institutional trial across 31 centres, 166 patients on intent-to-treat, four weekly doses of 375 mg/m2. Response rate 48%, median time to progression for responders 13.0 months at 11.8 months median follow-up. Grade 3 toxicity in 12% and grade 4 in 3%, mostly first-infusion fever and chills. Only one patient developed a human anti-chimeric antibody.

R-CHOP: adding rituximab to chemotherapy improved survival in aggressive lymphoma
In plain words
In 399 patients aged 60 to 80 with diffuse large B-cell lymphoma, adding the antibody to standard chemotherapy raised complete response from 63% to 76% and lengthened both event-free and overall survival.
What was measured
Complete response 76% versus 63%, p = 0.005
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
Randomised trial, 197 patients to eight cycles of CHOP and 202 to CHOP plus rituximab. Complete response 76% versus 63% (p = 0.005). At median follow-up of two years, event-free and overall survival were both significantly higher in the rituximab arm, without a clinically significant increase in toxicity. R-CHOP has been the global standard of care since.

EXPLORER and LUNAR: rituximab failed its two randomised trials in lupus
In plain words
B cells are central to lupus and rituximab depletes B cells, so it was expected to work. Two properly designed randomised trials, one in general lupus and one in lupus kidney disease, both failed to beat placebo.
What was measured
No difference from placebo on primary or secondary endpoints in either trial
Effect estimate
No reviewed effect estimate exists for this record.
Limits
This entry records a failure.
From the source
EXPLORER randomised 257 patients with moderately-to-severely active extrarenal systemic lupus erythematosus 2:1 to rituximab or placebo on aggressive background immunosuppression, and found no difference on the primary or secondary BILAG endpoints. LUNAR tested rituximab added to mycophenolate and steroids in proliferative lupus nephritis and likewise missed its primary renal response endpoint. Rituximab is nonetheless widely used off-label in refractory lupus on the strength of uncontrolled series, which is precisely the gap this record exists to mark.

From cancer drug to autoimmune platform, and then to a target obinutuzumab and ocrelizumab improved on
In plain words
Rituximab was designed for lymphoma. Its success in rheumatoid arthritis and vasculitis reframed B-cell depletion as a general autoimmune strategy, and its off-label success in multiple sclerosis directly motivated ocrelizumab, a humanised successor that was then tested properly.
What was measured
Not recorded
Effect estimate
No reviewed effect estimate exists for this record.
Limits

From the source
Approval sequence ran from non-Hodgkin lymphoma in 1997 to rheumatoid arthritis in 2006 and ANCA-associated vasculitis in 2011. Off-label multiple sclerosis use, supported by a positive phase 2 trial that was never taken to phase 3 by the sponsor, provided the rationale for ocrelizumab, which was developed to registration. The shift is instructive: a widely used off-label indication was eventually resolved by developing a different molecule rather than by testing the original one.

Hepatitis B reactivation and progressive multifocal leukoencephalopathy carry boxed warnings
In plain words
Wiping out B cells removes part of the defence against viruses the body was already holding in check. Hepatitis B can reactivate and cause fatal liver failure, and a rare brain infection has occurred.

The older medicine-wide conclusion held in this record

Written for a clinical reader, and about the medicine as a whole rather than about one indication, population and set of trials. RNAWiki does not treat it as a programme conclusion and no reviewer has signed it off in that form. It is here word for word because it is what the record holds.

The first therapeutic monoclonal antibody approved for cancer: adding it to CHOP chemotherapy raised complete response in elderly diffuse large B-cell lymphoma from 63% to 76% and lengthened overall survival.

What do 43919 spontaneous reports say about Rituximab — and not say?


These are reports people sent to a regulator. They do not show the medicine caused the reaction. Nobody counted how many people took the medicine and reported nothing. The same event can be reported more than once, and many reports are incomplete. News coverage, lawsuits and new warnings change how often people report. A count is not a rate and not a risk.

Rituximab appears in spontaneous reports to regulators. Across the 10 most-reported reaction terms, 43919 reaction mentions were counted: rheumatoid arthritis 7974; pain 5694; drug intolerance 4439; infusion related reaction 4090. open-targets-adr · CHEMBL1201576 · 2026-06-24
